The quartz compulsion incantation lets you telepathically contact the subject by gazing through a quartz shard, regardless of where the subject is located. You can telepathically converse for 16 minutes with the subject. Your telepathic contact can also contain a suggestion (as per the suggestion psionic power), which the subject does her best to carry out. A successful Will save negates the suggestion effect but not the contact itself. Telepathic communcation is possible even if the creature’s Intelligence score is as low as 1, but you must have a language in common with the subject to communicate. If the message is impossible or meaningless according to the circumstances that exist for the subject at the time the quartz compulsion comes, the message is understood but the suggestion is ineffective.

Focus: A carefully cut shard of quartz (600 gp).

Backlash: Caster is exhausted.

Failure: Reversal. You converse with the subject normally, but the suggestion attempt automatically fails, and the subject can instead compel you (as per the suggestion psionic power). You don’t get a saving throw, and spell resistance does not apply. Depending on the specific suggestion, you may not realize that your attempt failed or that you’ve been compelled.
